Description

Technical Field

[0001] The utility model relates to the field of material level detection, and specifically, to an auxiliary device for detecting the material level of a cement silo. Background Art

[0002] During the production process of concrete, cement is directly poured into a closed cement silo. To confirm the material level of the cement silo, workers need to climb the external ladder of the cement silo to a position dozens of meters high and knock on the silo body. This method not only consumes manpower but also poses a risk of falling from a height.

[0003] To avoid manually climbing to determine the material level, Patent CN204064400U discloses an auxiliary device for judging the material level of a cement silo. It adjusts the position of a detection hammer by the sliding of a steel wire rope on a pulley, and then swings the steel wire rope to make the detection hammer knock on the silo body. When a clear knocking sound is heard, it is determined that there is no material at this position, and the height line position is recorded; adjust the position of the detection hammer to knock on the silo body. When a dull knocking sound is heard, it is determined that there is material at this position, and the height line position is recorded; then finely adjust the position of the detection hammer between the above positions and continue to knock on the silo body until the material position in the cement silo is determined, and finally record the height line position.

[0004] However, the position of the pulley in this patent is fixed at the top of the cement silo and cannot move. The part of the cement silo knocked by the detection hammer is relatively fixed. However, during the process of adding and consuming cement in the silo, the material level of the cement is often not a straight line. The material level may be concave on one side and convex on the other side. The detection hammer only knocks on the relatively fixed part of the axial direction of the cement silo below the pulley and cannot accurately detect the actual amount of material in the cement silo. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an auxiliary device for detecting the material level of a cement silo with a flexibly adjustable knocking position, so as to solve the technical problem that the knocking position of the detection hammer in the prior art is relatively fixed, resulting in inaccurate detection of the actual remaining material amount in the cement silo.

[0006] To solve the above technical problems, the present application provides the following technical solutions:

[0007] An auxiliary device for detecting the material level of a cement silo, comprising a fixed pulley assembly, a towing rope, a detection hammer and a mounting frame;

[0008] The mounting frame is fixedly installed on the top of the outer wall of the cement silo;

[0009] The fixed pulley assembly includes a fixed pulley and a bracket. The fixed pulley is fixedly installed on the bracket, and the bracket is slidably connected to the mounting frame;

[0010] The detection hammer is fixedly arranged on the towing rope, and the towing rope is connected end to end and sleeved on the fixed pulley.

[0011] Further, the sliding connection method is specifically that a slide rail is provided on the mounting frame, the bracket is fixedly connected with a slider, and the slider on the bracket is slidably connected with the slide rail on the mounting frame;

[0012] Further, the towing rope is a steel wire rope.

[0013] Further, the diameter of the towing rope is 4 mm to 8 mm.

[0014] Further, a rope limiting ring is further included, and the rope limiting ring is fixedly arranged at the bottom of the cement silo.

[0015] Further, the detection hammer is made of metal.

[0016] Further, the surface of the detection hammer is subjected to a smooth treatment.

[0017] Further, 4 or 6 or 8 scale lines are uniformly arranged on the circumferential direction of the outer surface of the cement silo.

[0018] Preferably, 6 scale lines are uniformly arranged on the circumferential direction of the outer surface of the cement silo.

[0019] The technical solution of the embodiment of the present utility model has at least the following advantages and beneficial effects:

[0020] By arranging the mounting frame, the bracket fixedly connected with the fixed pulley is slidably connected to the mounting frame, and the staff pulls the towing rope to tow the bracket to slide on the mounting frame, which can drive the pulley to move circumferentially on the top of the cement silo, so as to flexibly adjust the circumferential knocking position of the detection hammer on the cement silo, obtain the material level conditions of the cement in the cement silo at each circumferential site, and can more accurately detect the actual remaining material quantity in the cement silo.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0026] Embodiment 1

[0027] A cement silo material level auxiliary detection device includes a fixed pulley assembly 1, a towing rope 2, a detection hammer 3, and a mounting bracket 4;

[0028] The mounting bracket 4 is fixedly installed at the top of the outer wall of the cement silo;

[0029] The fixed pulley assembly 1 includes a fixed pulley 11 and a bracket 12. The fixed pulley 11 is fixedly installed on the bracket 12, and the bracket 12 is slidably connected to the mounting bracket 4;

[0030] The detection hammer 3 is fixedly arranged on the towing rope 2, and the towing rope 2 is looped around the fixed pulley 11 with its head and tail connected.

[0031] In this embodiment, the specific way of the sliding connection between the bracket 12 and the mounting bracket 4 is that a slide rail 41 is provided on the mounting bracket, and the bracket 12 is fixedly connected to a slider 13, and the slider on the bracket 12 is slidably connected to the slide rail 41 on the mounting bracket 4;

[0032] The towing rope 2 in this embodiment is a steel wire rope, and its diameter is preferably 4 mm to 8 mm.

[0033] It further includes a rope limiting ring 5. The rope limiting ring 5 is arranged at the bottom of the cement silo. When the towing rope 22 is not in use, the towing rope 22 is placed in the rope limiting ring for storage.

[0034] The detection hammer 33 in this embodiment is made of metal and has a smooth surface. After the detection hammer 33 has a smooth surface, the knocking damage to the cement silo body can be reduced during knocking.

[0035] Six scale lines are evenly arranged circumferentially on the outer surface of the cement silo in this embodiment.

[0036] Method for judging the actual remaining material quantity in the cement silo:

[0037] An operator holds the towing rope 2 in the above device and adjusts the longitudinal height of the detection hammer 3 by sliding the towing rope 2 up and down on the fixed pulley 11. After adjusting the detection hammer 3 to a longitudinal height, the steel wire rope is swung to make the detection hammer 3 knock on the silo body. When a clear knocking sound is heard, it is judged that there is no material at this position, and the height line position H1 is recorded; the detection hammer 3 is adjusted downward to a longitudinal height and the steel wire rope is swung to make the detection hammer 3 knock on the silo body. When a dull knocking sound is heard, it is determined that there is material at this position, and the height position H2 is recorded; then the position of the detection hammer 3 is adjusted between H1 and H2 and the silo body is knocked continuously until the height position H3 of the material in the cement silo is preliminarily determined.

[0038] Then, at the height position H3, the towing rope 2 is pulled to tow the bracket 12 of the fixed pulley assembly 1 to slide on the mounting frame 4, driving the fixed pulley assembly 1 to move circumferentially on the top of the cement silo, so as to change the circumferential position of the fixed pulley 11 on the top of the cement silo, and the wire rope is swung at different circumferential positions to make the detection hammer 3 strike the silo body.

[0039] According to the same method as determining the height position H3 above, the height positions H4, H5, H6... of the materials in the cement silo at different circumferential positions are determined. According to the material height positions H3, H4, H5, H6... at different circumferential positions, the actual remaining material quantity in the cement silo is judged.

[0040] In summary, the auxiliary detection device for the material quantity of the cement silo in this application can obtain the material level conditions of the cement inside the cement silo at each circumferential point, and can more accurately detect the actual remaining material quantity in the cement silo.
